Abstract

During storage, the seeds experienced deterioration by time and or by pests. Sorghum seed is very susceptible to pest attacks in warehouse. In addition to prevent pest attacks, seed fumigation before storage can also give negative effects on seed viability. This study aimed to determine the effect of duration of fumigation with phosphine (PH3) on the viability of sorghum seeds during storage. This experiment was conducted at the Laboratory of Seeds and Plant Breeding, Faculty of Agriculture, University of Lampung from July 2016 to April 2017. Two factors consisted duration of fumigation and storage length those were arranged factorially and then it were applied in a randomized complete block design (RCBD). This experiment was conducted three replicates. Sorghum seeds that have been given treatment duration of fumigation of 24, 48, and 72 hours were wrapped in tight sealed plastic bags and placed in a storage room with a temperature of 26 ± 0.4°C. Viability of the seeds was then observed after 3, 6, and 9 months storage. The significant interaction effect of duration of fumigation and storage length on viability of sorghum seed showed that the effect of duration of fumigation was depended on storage length applied to the seeds. It was showed by variables of electrical conductivity, speed of germination, and germination capacity. The viability of the seed exposed to duration of fumigation 24 or 48 hours would not decrease significantly up to 9 months of storage. Whereas, viability of the seed exposed to duration or fumigation for 72 hours would decreased their viability after 6 months of storage. Effect of duration of fumigation on viability seemed earlier by the speed of germination than by germination capacity.
